Integrated cultivation of sea asparagus, celery, and Southern black drum in saline clear waters and biofloc‐based aquaponics

open access: yesAgronomy Journal, Volume 118, Issue 1, January/February 2026.
Abstract Aquaponics is an alternative agricultural practice that combines aquaculture with hydroponics. It increases productivity while treating macronutrient loads on effluents. Yet, little information is available on productivity of commercial aquaponic models using saline waters, especially with biofloc technology (BFT) systems, which are ...

Tails of Biodiversity: Vertebrate Community Assessment in a Neotropical River Basin via eDNA Metabarcoding

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
This study used environmental DNA (eDNA) metabarcoding to assess vertebrate biodiversity in headwater streams of the Rio Santo Antônio basin, southeastern Brazil, a tributary of the Rio Doce. A total of 119 vertebrate OTUs were identified, with oxidation–reduction potential emerging as the strongest environmental predictor of species richness.

Monoterpenes: Functional Additives for Reducing Antibiotics in Aquaculture

open access: yesReviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Aquaculture is a rapidly growing industry that supplies fish for global consumption. However, the intensive production practices have resulted in disease outbreaks, largely driven by the misuse of antibiotics. Natural alternatives, such as monoterpenes, which are biocompounds derived from essential oils obtained from plants like thyme and ...
